|
|
Condensate Pump Fail | • Verify that the condensate pump circuit breaker has not been tripped. |
| • Ensure that the wiring between the float switch for the condensate pump and |
| the controller is secure. |
| • Confirm that the condensate removal lines are free of debris and are |
| unobstructed. |
| • Confirm the line voltage at the condensate pump. |
| • Ensure that the condensate float switch is moving freely and does not bind. |
| • Confirm that the condensate pump reservoir is clean and free of debris. |
| • Replace the condensate pump. |
|
|
Env Humidity High | • Verify that no supply air is fed directly into the return air stream. |
| • Ensure that the alarm delay is not set too low. The delay should be long |
| enough to allow the humidity in the room to stabilize after |
| • Verify that the alarm threshold for the humidity of the environmental sensors |
| (return or remote) is set 7 - 10 % above the dehumidify setpoint. |
| • Ensure that the reheat mode is enabled and the Reheat setpoint is 2 degrees |
| less than the cool setpoint. |
| • Ensure that there is a proper vapor barrier within the conditioned space. |
| • Ensure that the dehumidify mode is enabled and working properly. |
| • Verify that the Module is configured and equipped for the dehumidify mode. |
| • Ensure that the dehumidify mode is not disabled because of an active |
| customer input mapped to nonessential lockout. |
|
|
Env Humidity Low | • Ensure that the alarm delay is not set too low. The delay should be long |
| enough to allow the humidity in the room to stabilize after |
| • Verify that the alarm threshold for the humidity of the environmental sensors |
| (return or remote) is set 7 - 10 % lower than the humidify setpoint. |
| • Ensure that there is a proper vapor barrier within the conditioned space. |
| • Verify that the Module is configured and equipped for the humidify mode. |
| • Ensure that the humidify mode is enabled. |
| • Check the capacity output of the humidifier, and decrease the humidifier |
| sensitivity setpoint if required. |
| • Ensure that the humidify mode is not disabled because of an active |
| |
| • Check the alarm status and event log for humidifer alarms and perform |
| required actions. |
|
|
Env Temperature High | • Check whether the Module is cooling. Look for a temperature differential of |
| |
| • Ensure that there is no concentrated heat source in the return air stream of the |
| Module. |
| • Ensure that the alarm delay is not set too low. The delay should be long |
| enough to allow the room temperature to stabilize after |
| • Verify that the temperature alarm threshold for the environmental (return or |
| remote) sensors is 7 - 10°F above the cool setpoint. |
| • Ensure that the cooling mode is enabled and working properly. |
| • Ensure that the cooling mode is not disabled because of an active customer |
| input mapped to nonessential lockout. |
| • Check the alarm status and event log for cooling failure alarms and perform |
| required actions. |
